My present invention relates to a fluid controlling valve, and moreparticularly to an improved valve for withdrawing fluids from a sealedcontainer, such as a barrel or the like, wherein it is necessary toprovide an air vent to facilitate a withdrawal of the fluid therefrom.

An object of my invention is to provide a new and novel form of valvefor withdrawing a fluid from a sealed container having means for'ventingthe container when fluid is being withdrawn from the container.

Another object of my invention is to provide a new and novel form ofvented valve having means wherein'the vent may be optionally renderedoperable and/or inoperable when the valve is opened.

Other objects and advantages of my invention will be in part evident tothose skilled in the art and in part pointed out in thefollowing'description taken together with the accompanying drawingwherein there is shown, by way of illustration and not of limitation, apreferred embodiment thereof.

In the drawing, wherein like numerals refer to like parts throughout theseveral views;

Figure 1 is a vertical sectional view of valve constructed in accordancewith a preferred embodiment of my invention,

Figures 2 and 3 are fragmentary sectional views taken from Figure 1,showing two positions of the parts when the valve is open,

Figure 4 is a view similar to Figure 1, showing a modified form of myinvention,

Figures 5 and 6 are fragmentary sectional views taken from Figure 4,showing the relation of parts thereof when the valve is in its openposition and the vent respectively opened and closed, and

Figure 7 is a vertical sectional view of a further modified form of myinvention showing the parts of the valve in their valve closingpositions.

As a preferred embodiment of my invention, I have shown in Figure 1 ofthe drawing a valve bcdy member Iii having a screw threaded extensionthat is adapted to be turned into the outlet of a barrel or the threadedoutlet of a similar container. The valve body l0 also has a dischargeoutlet spout I2 over the inner end 01' which a valve member I3 isdisposed. The valve member I3 is biased into sealing engagement 'withthe inner end of the discharge outlet l2, by

means of a spring l4, and connected to the valve member l3 there is avalve operating stem IS. The valve operating stem l5 extends through thespring l4 and out of the valve; body ID at a point opposite thedischarge outlet l2. At its upper end the valve operating stem I5 isprovided with an operating lever l6 that is adapted to raise the stem l5by compressing the spring l4 and thus opening the discharge outlet whenpressure is applied thereto.

Extending through the wall of the valve body Ill there is a vent formingpassageway I! which terminates at one end adjacent the inlet to thevalve and at its other end adjacent the valve member operating stem l5.Cooperating with the vent forming passageway 17 there is a vent aperturel8, which is formed in the valve operating stem l5, where it will alignwith the vent forming passageway I! when the valve member I5 is raisedto its valve open position. The vent aperture I8 is shown as extendingdiagonally and diametrically through the valve operating stem I5, sothat when the valve operating stem I5 is in the position as shown inFigure 2 of the drawing, a vent passageway will be established from theatmosphere to the inlet end of the valve body l0.

At this point it should be stated that the operating valve lever I6 hasa heel-like portion 1 9 that is adapted to be thrown over center to holdthe operating lever IS in its depressed position when the operator hasreleased same. The heel I9 upon the operating lever l6 engages anannular boss 20 upon the valve body I0 and, as a result, it is possibleto rotate the operating lever l6 and the valve operating stem l5 intothe position illustrated in Figure 3 of the drawing, withoutnecessitating or permitting a closing of the discharge outlet l 2 of thevalve. In this manner it is possible to optionally open and/or close thevent passageway formed, as above described, without closing thedischarge outlet l2.

In Figure 4 of the drawing, the valve body I0 is similar to thatillustrated in Figure 1, except that it is provided with a screwthreaded portion 2| through which a threadedvalve operating stem 22 isadapted to extend. The threaded valve operating stem 22 has an operatinghandle 23 and at its lower end it carries a valve member 24 that isadapted to close the discharge outlet l2 when the threaded valveoperating stem 22 is turned downwardly into the valve body Hi. In thisem- .bodiment of my invention, like the one previously referred to, thebody member I0 has a vent forming passageway I! that communicates withthe threaded opening through which the valve operating stem 22 projects.

In order to provide for an opening of the vent forming passageway I! tothe atmosphere, when the valve member 24 is in itsdischarge outletopening position, the threaded valve operating stem 22 is provided witha cutaway portion 25 that is adapted to align with the vent formingpassageway l1 and thus establish a communication with the atmosphereexternally of the valve body ID. This cutaway portion 25 is provided byslotting the threaded valve operating stem 22 for a. short distance at apoint adjacent the end of the vent forming passageway l1. Such aslotting will destroy only a very small portion of the screw threads atthis point and, as a result, it will be possible, after the valve member24 has been moved into its open position, to optionally open and/orclose the air vent provided by the vent forming passageway l1 and thecutaway portion 25 upon the threaded valve operating stem 22. Theposition of thescrew threaded operating stem 22, when the valve and thevent are opened, is clearly illustrated in Figure 5 of the drawing, andthe position of the threaded valve operating stem 22, with the valveopen and the vent closed, is clearly shown in Figure 6 of the drawing.

In Figure '7 of the drawing, I have shown an embodiment of my invention,having a valve body 26 that is provided with a threaded inlet extensionfor attachment to a barrel or like container.

In addition to this threaded inlet extension, the body member 26 alsohas a discharging outlet spout 21 at its outer end. Located within thevalve body 26 there is an annular valve seat 28 against which a valvemember 29 is adapted to engage to close the valve. The valve member 29is mounted upon a tubular valve stem 30 and it is biased against theannular valve seat 28 by a spring 3|. This tubular valve stem extendsthrough a thickened portion 32 at the outer end of the valve body 26. Atthis point the valve body 26 is providedwith a bushing 33, in which thetubular valve stem 30 will snugly fit and permit it to be both rotatedand moved axially therein. Extending radially through the thickenedportion 32 of the valve body 26 and the bushing 33 there is a ventforming passageway 34 that is adapted to cooperate, as will hereinafterappear, with a vent aperture 35 formed at a properly located pointthrough the tubular valve stem 30. Mounted upon and closing the outerend of the tubular valve stem 30 there is an operating push button 36 bymeans of which the tubular valve stem 30 may be moved axially againstthe action of the valve member biasing spring 3|.

With this last above described embodiment of my invention, it will beseen that by pressing inwardly upon the operating push button 36, itwill be possible to move the valve member 29 into its valve openingposition and at the same time open the vent forming passageway 34 to theinterior of the tubular valve stem 30 and permit the entrance of air tothe interior of the container from which fluid is being withdrawn. Itwill also be noted, since the vent aperture 35 comprises only a smallopening in one side of the tubular valve stem 30, that by a slightrotationof the operating push button 36 it will be possible to move thevalve member 29 into its-valve open position without establishing aventing communication with the atmosphere through the tubular valve stem30.

From the above it will be seen that I have provided a novel ventedvalve, which, in addition to controlling the discharge of fluid from thecontainer, will also control the admission of air to from the containerwill be admitted thereto and also provides against contamination of'thefluid when the valve is closed.

While I have, for the sake of clearness and in order to disclose myinvention so that the same can be readily understood, described andillustrated specific devices and arrangements, I desire to have itunderstood that this invention is not limited to the specific meansdisclosed, but may be embodied in other ways that will suggestthemselves to persons skilled in the art.
